 this appears to be the root cause:
 Disassembly of section .init:
 
 00400609 <_init>:
   400609:       0002            addiu   s0,sp,8
   40060b:       3c1c            ld      s0,224(a0)
   40060d:       86a7            lb      a1,7(a2)
   40060f:       279c            beqz    a3,400549 <_DYNAMIC+0x399>
   400611:       e021            addu    s0,s1
 ...
 
 without -static-libgcc _init looks like this:
 Disassembly of section .init:
 
 00400698 <_init>:
   400698:       3c1c0002        lui     gp,0x2
